The above research on combined power generation systems only stays in dispatch optimization and configuration of energy storage capacity, and does not optimize the capacity configuration of other power sources in the power generation system, nor does it consider the fluctuation of the power grid caused by load uncertainty.
The system consists of three components: a control center, a PV system and a BESS. Depending on the PV system’s output and supply forecast, the control center prompts the change of the incoming and charging power at the battery by transmitting the SetData and SetValues services.
The logical nodes of the battery system ZBAT and the battery charger ZBTC are responsible for battery data. The node ZBAT contains general information on the battery, including battery type, capacity and charging (power injection). They can also be used to perform logical node tests and to switch the system on and off.
Abstract: Cellular base stations (BSs) are equipped with backup batteries to obtain the uninterruptible power supply (UPS) and maintain the power supply reliability. While maintaining the reliability, the backup batteries of 5G BSs have some spare capacity over time due to the traffic-sensitive characteristic of 5G BS electricity load.
While maintaining the reliability, the backup batteries of 5G BSs have some spare capacity over time due to the traffic-sensitive characteristic of 5G BS electricity load. Therefore, the spare capacity is dispatchable and can be used as flexibility resources for power systems.
The control center communicates with the PV system by a Modbus protocol and with the BESS by IEC 61850. The IEC 61850 data structures provided by the BESS were created beforehand by a configuration file. Fig. 5 presents a schematic of this structure. Fig. 5. use case “meeting the supply forecast”. 5.1.
